I'm to do a analysis of the cross boarder M&A activity in terms of no of transactions and moved capital (deal value). As so I was looking into the sankey chart which could be useful; i would imagine the outflows on the left and the inflows in the right, as such e.g. the US outflows would show the total outflow in the right hand column and in the strings - the curves, represent that x amount of transactions (and/or value) goes to UK, y goes to Canada and z goes to France.

Do any of you have any better suggestions than the above? Would be very much appreciated!
